Loading and Playing Multiple Sounds

Question

I have written a loadSound function which handles loading and playing multiple sounds. This function works fine when I call this function in another keyframe i.e. the frame in which the function is not written. But when I call the function on the same frame in which the function is written the sounds gets mixed up. For example the function is written in 1st keyframe. If I call this function in 2nd, 3rd and 4th keyframe (with different sounds) it works fine. But when i call the same function in 1st, 2nd and 3rd keyframe it all gets messed up.
In 1st keyframe the sound plays properly. When I move to 2nd Keyframe the 2nd sound plays. But when I move back to the 1st keyframe the 2nd and 1st keyframe sounds all get mixed up. This doesn't happen when I call the function in 2nd, 3rd and 4th keyframes.
Below is my function:
import flash.events.Event;
import flash.media.Sound;
import flash.net.URLRequest;
import flash.events.ProgressEvent;
import flash.events.IOErrorEvent;
import flash.errors.IOError;
import flash.media.SoundChannel;
import flash.media.SoundMixer;
import flash.events.TimerEvent;
import flash.utils.Timer;
import flash.display.MovieClip;
import flash.media.SoundTransform;
stop();
var s:Sound;
var localSound:SoundChannel = new SoundChannel();
var req:URLRequest;
var loadedPct:uint;
var currentFrameArr:Array = ["One","Two","Three"];
var urlArr:Array = ["sound/m01_t01_s01.mp3","sound/m01_t01_s02.mp3","sound/page10_11.mp3"];
function loadSnd(currentFrm:String)
s = new Sound();
s.addEventListener(ProgressEvent.PROGRESS, onSoundProgress);
s.addEventListener(Event.COMPLETE, onSoundLoaded);
s.addEventListener(IOErrorEvent.IO_ERROR, onIOError);
localSound.stop();
for (var i:uint=0; i<currentFrameArr.length; i++)
  if (currentFrm == currentFrameArr[i])
   req = new URLRequest(urlArr[i]);
s.load(req);
function onSoundProgress(evt:ProgressEvent):void
  loadedPct = Math.round(100 * (evt.bytesLoaded / evt.bytesTotal));
  trace("The sound is " + loadedPct + " % loaded");
function onSoundLoaded(evt:Event):void
  localSound = s.play();
function onIOError(evt:IOErrorEvent):void
  trace("The sound could not be loaded: " + evt.text);
Call to this function in different frames:
loadSnd("One");
loadSnd("Two");
etc
If I pass the parameter 'One' in loadSnd it plays the 1st element in urlArray, 'Two' 2nd element and so on.
I have been scratching my head since long over this.
Can anybody please pinpoint the error.

Got the solution. The SoundMixer.stopAll(); statement did the trick. The complete workable function is pasted below:
import flash.events.Event;
import flash.media.Sound;
import flash.net.URLRequest;
import flash.events.ProgressEvent;
import flash.events.IOErrorEvent;
import flash.errors.IOError;
import flash.media.SoundChannel;
import flash.media.SoundMixer;
import flash.events.TimerEvent;
import flash.utils.Timer;
import flash.display.MovieClip;
import flash.media.SoundTransform;
stop();
var s:Sound;
var localSound:SoundChannel = new SoundChannel();
var req:URLRequest;
var loadedPct:uint;
var currentFrameArr:Array = ["One","Two","Three"];
var urlArr:Array = ["sound/m01_t01_s01.mp3","sound/m01_t01_s02.mp3","sound/page10_11.mp3"];
function loadSnd(currentFrm:String)
  s = new Sound();
  s.addEventListener(ProgressEvent.PROGRESS, onSoundProgress);
  s.addEventListener(Event.COMPLETE, onSoundLoaded);
  s.addEventListener(IOErrorEvent.IO_ERROR, onIOError);
  SoundMixer.stopAll();
  localSound.stop();
  for (var i:uint=0; i<currentFrameArr.length; i++)
  if (currentFrm == currentFrameArr[i])
  req = new URLRequest(urlArr[i]);
  break;
  s.load(req);
function onSoundProgress(evt:ProgressEvent):void
  loadedPct = Math.round(100 * (evt.bytesLoaded / evt.bytesTotal));
  trace("The sound is " + loadedPct + " % loaded");
function onSoundLoaded(evt:Event):void
  localSound = s.play();
function onIOError(evt:IOErrorEvent):void
  trace("The sound could not be loaded: " + evt.text);
Calling the function
loadSnd("One");
loadSnd("Two"); etc
